उत्पाद का वर्णन
Custom Main Steam Control Valve Stems for Steam Turbines
Product Overview

Our tailor-made main steam control valve stems are core critical moving components for supercritical & ultra-supercritical steam turbine main steam valves, widely used in thermal power plants, cogeneration units and industrial steam turbine systems.

Manufactured via integral die forging and ultra-precision CNC machining, each valve stem is fully customized based on customers' drawings, unit parameters and extreme operating conditions. It precisely transfers actuator driving force to adjust steam flow, stabilize turbine power output and maintain reliable sealing under long-cycle frequent opening/closing operations in high-temperature, high-pressure main steam environments.

Core Customization Strengths
Full Customization Service
  • Customize overall length, stepped shaft structure, thread size, sealing journals, gear tooth section and conical valve head
  • Support OEM & ODM for all mainstream turbine brands
  • Multiple surface strengthening treatments optional: QPQ nitriding, hard chrome plating, Stellite alloy surfacing, electroless nickel plating
Premium Heat-Resistant Alloy Materials

We select materials according to your actual working temperature (540℃ / 566℃ / 600℃+) and pressure (16-32MPa):

Material Type Examples
Heat-resistant alloy steel 12CrMoV, F91, F92, 35CrMoA
Martensitic stainless steel 12Cr13, 17-4PH
High-temperature superalloy For ultra-supercritical harsh working conditions

Full material test certificates (MTC), chemical composition and mechanical property reports provided for every batch.

Advanced Manufacturing Technology
  • Integral open-die forging eliminates casting defects like pores and segregation, optimizes internal metal grain flow
  • Ultra-precision cylindrical grinding for matching surfaces, tolerance controlled within ±0.002mm
  • Mirror polished shaft surface reduces friction, effectively prevents valve sticking
Excellent Performance Under Extreme Conditions
High Temperature Stability

Consistent mechanical properties under 500-620℃ superheated steam

High Pressure Resistance

Adaptable to ultra-high pressure main steam pipelines

Extended Service Life

3-5 times longer service cycle than standard valve stems, cutting power plant maintenance downtime and spare parts costs

Strict Quality Inspection System
  • Raw material incoming test: Spectrum analysis, hardness test, ultrasonic flaw detection
  • Semi-finished product inspection: Full dimension measurement via coordinate measuring machine (CMM)
  • Surface treatment performance test: Hardness, wear resistance and high-temperature oxidation simulation tests
  • 100% non-destructive testing (UT & MT) for finished products before delivery
